Company Coding Interviews

Coding interview problems with full optimal solutions, organized by company. Each problem ships with multiple approaches (brute-force first, then the optimal), explicit complexity tables, company-specific tips on what each interview team values, common mistakes, and follow-up questions an interviewer might pivot to. Sourced from public interview reports on Glassdoor, Levels.fyi, Blind, and r/cscareerquestions.
